* CompleteMonster: Guren, [[TheDragon second-in-command]] to [[BigBad Hakumen no Mono]], was already a vicious mercenary and murderer in life before he found [[ArtifactOfDoom the Beast Spear]]. Enjoying nothing so much as killing others, he used the Beast Spear on human beings until it [[EvilMakesYouMonstrous devoured his humanity, leaving him as the monstrous, black-furred Guren]]. Guren would spend the centuries hunting down and devouring humans: men, women and children alike. Finally, he devoured the family of a man who would take the name Hyou and the two inflicted wounds and scars on one another, earning a mutual hatred. Hyou would hunt down Guren, following the trail of his atrocities. In their final duel, Guren tried to gain the upper hand by holding a woman and her child hostage, knowing Hyou would remember his own family. Guren planned to kill Hyou when his guard was down, before devouring the humans as a post-victory treat.* EarWorm: The first opening to the OVA, [[https://www.youtube.com/watch?v=6FCHq5uKi9U Yuuki no Fighter]], ''will'' stick in your head for a long time.* EnsembleDarkhorse: During the manga's original run, Izuna became unexpectedly popular and ranked quite high on the popularity polls, which resulted in him appearing more often and joining the titular duo in some adventures.* ItsShortSoItSucks: The decision to make the new anime a CompressedAdaptation with various parts cut from the original manga didn't sit well with some fans.* {{Narm}}: In some early panels, Tora's ears are visible. Giant, floppy, rabbit ears.* ThisIsYourPremiseOnDrugs: One ''Anime UK'' magazine review of the {{OVA}}s described it as "''ComicStrip/CalvinAndHobbes'' on acid".* UncannyValley: So, OurMonstersAreWeird yes... Now add assorted limbs, faces and naughty bits that look COMPLETELY like an ordinary human's on almost random places on the bakemono's body, and it gets even freakier. Examples: A perfectly bad-ass looking crab bakemono which is then revealed to have HUMAN FACES on the inside of its claws; numerous lesser bakemono with mutiple HUMAN ARMS AND LEGS instead of more practical for fighting claws.* TheWoobie: So, ''SO'' many characters.** You will want to give Tora [[spoiler:AKA Shagakusha]] a hug once you learn his backstory.** Same goes for Hyou. ** Some of the bakemono enemies even, though it doesn't excuse their reaction of massacring all humans they meet.----
